these are the options... The length of the side of the second square is 3 times greater than the length of the side of the first square. The length of the side of the second square is 12 times greater than the length of the side of the first square. The length of the side of the second square is 9 times greater than the length of the side of the first square. The length of the side of the second square is 6 times greater than the length of the side of the first square.

since \(A=l^2\) and \(A'=l'^2\) when \(A=9A'\) sub them in to get the relationship between l and l'

what am i supposed to sub in?
 one year ago

Shadowys Group TitleBest ResponseYou've already chosen the best response.2
the l and l ' like this: \(A=9A'\) \(l^2 = 9 l'^2\)

im like really slow and have no idea wut im doing._

Shadowys Group TitleBest ResponseYou've already chosen the best response.2
lol. i guess i'll try to do it step by step. since \(A=l^2\), \(A_1=l_1^2\) (this is the first square)............(1) \(A_2=l_2^2\) (this is the second square)........(2) since the area of the second square is nine times the first, (it's the only given condition, so we start from that.) \(A_2=9A_1\) subbing (1) and (2) into it, we get, \(l_2^2=9l_1^2\) what did you get after taking thesquare roots of both sides?

sorry im back and thank you.

Just take the square root both the sides and tell us what you got as @Shadowys said above..

Getting ?? @Brianna9898

I have no idea!

Are you getting till here" \[l_2^2=9 l_1^2\]
 one year ago

Brianna9898 Group TitleBest ResponseYou've already chosen the best response.0
why is there a 1 & 2 at the bottom
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
See when you will take square root you will get like: \[\large \sqrt{l_2^2} = \sqrt{9 l_1^2}\] Can you tell what is this: \[\large \sqrt{l_2^2} = ??\]
 one year ago

Brianna9898 Group TitleBest ResponseYou've already chosen the best response.0
... and how am I supposed to square root an l ??
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Oh that.. \(l_1\) is showing length of first square. \(l_2\) is for length of second square.
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
you can actually.. See, What is square root of this: \[\large \sqrt{2^2} = ??\]
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Similar way what will be square root of this: \[\large \sqrt{l_2^2} = ??\]
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Or you can say \(l_2\).. Good..
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Similarly can you tell for: \[\large \sqrt{9l_1^2} = ??\]
 one year ago

Brianna9898 Group TitleBest ResponseYou've already chosen the best response.0
so you have to keep the 2 at the bottom

Shadowys Group TitleBest ResponseYou've already chosen the best response.2
the one and two are sub scripts to differentiate between the first length and the second, thus, 1 and 2 respectively.
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
see, 1 and 2 is differentiating lengths of the two square you are given with, so don't think here of just l think here of \(l_1\) and \(l_2\)..
 one year ago

Brianna9898 Group TitleBest ResponseYou've already chosen the best response.0
so it would be \[9l _{1} ??\]
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
You forgot to take square root of 9. \(l_1\0 is good though..
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
What is square root of 9?
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Yep after square root you will get like: \[\large l_2 = 3 \times l_1\]
 one year ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
So, which answer choice is this?
 one year ago

Brianna9898 Group TitleBest ResponseYou've already chosen the best response.0
the first one?

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
No, just only one..
